PACKING & LABEL SPECIFICATIONS TA23-11EWA
Remarks:
If special sorting is required (e.g. binning based on forward voltage, luminous intensity/ luminous flux or wavelength),
the typical accuracy of the sorting process is as follows:
1. Wavelength: +/-1nm
2. Luminous Intensity/ Luminous Flux: +/-15%
3. Forward Voltage: +/-0.1V
Note: Accuracy may depend on the sorting parameters.
